Window sashes need to be inspected regularly for signs of mold, mildew, and damage. If you catch these issues early, you can save money on future repairs.

The sash is an inside frame that can move vertically up and down in windows that open. This article will show you how to do simple repairs to sash.

Weather Stripping

Wooden window sashes can add an elegant appearance to your home. They are also durable and can last many years if they are properly maintained. They may, however, be damaged or degraded over time, due to exposure and normal wear and tear. www.repairmywindowsanddoors.co.uk can restore windows to their original state and maintain their beauty much longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it can cause drafts and other problems. Begin by identifying the window's brand and the manufacturer's date (etched on the corner of the glass or on the aluminum spacers between panes). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.

Then, you can remove the sash from its holder and place it on an even surface that allows you to see all four sides. If your sash was double-hung, remove the weights with their ropes that should be buried in the jamb lining. Once you've taken the sash off, use a utility knife to remove the weather stripping that was formerly in place at the corners. Then, remove it by hand or using a putty blade.

Once the sash is clear, you can replace the parting stops. These are long pieces wood that divide the two sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trim from the lumberyard. However, you could substitute for a scrap piece of lumber.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound using your putty tool and let it dry for at least a day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This will help protect the putty, and give your sash a modern appearance.

Sash Hardware


The hardware that supports window sashes susceptible to wear and tear due to time and usage, and the result can be a window or door that isn't able to open or close easily. It's good to know that replacing or repair of this hardware is typically simple and inexpensive. If a sash isn't easy to operate try spraying oil into the jamb channel, and then slide it open to see if that resolves the issue. If not, the issue is likely to be with the balance of the sash and you'll need to take out the sash in order to access this hardware.

The ideal situation is for window sashes to move open and shut with minimal effort however, this can be an issue if the weights become worn or if the sash meeting rail isn't properly glazed. This problem can be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for a particular sash.

If the hinges on the window begin to move, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To fix this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash was screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Old windows, particularly those in older homes, can be difficult to close and open due to hinges that are sagging and a general lack of energy efficiency. Sometimes, a few simple fixes can help these windows function smoothly and help homeowners save money on energy bills.

To make these repairs to the sash it is important to have all of the necessary tools lined up before you begin. Mark the location of the hinge channel on the frame (Photo 1) with a pencil. This will make it easier to place the channel in the correct position after you've finished. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. Soften any putty that has been hardened with a heat gun set to medium and equipped with a nozzle shield. Take off the old sash and keep it in a bag labeled.

Sash Weights

Sash weights can be replaced to improve the operation of your window sash and reduce energy costs. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and linked to the moveable the sash with rope. These weights act as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners, and are turned into scrap when they fail. Consequently you may have to locate replacements.

A sash weight that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits correctly. You will also need a new piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights onto the sash cord.

Mortise and Tenon joints can be used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs holding the parts together. The majority of these pegs are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife and a mallet.

Once the sash has been released, you can remove the sash stops and access the weight pockets. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.

When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Be sure to weigh the sash before you do this, since the old weights could be different sizes than the one you need. Once the new weight is installed, tie a string to it and thread it through the sash pulley. Then, attach the string to the boxed frame. Leave a few inches of space at the end of the string to allow for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord attached to the weights that helps keep the sashes in balance within the jamb. Over time, these chains can get damaged and make it impossible to raise the windows. A new sash cable will give you the ability to move and lower the sash and keep it in place when opened.

The first step to replace cords for sash is to locate and take out the access panels located in the jambs. These are usually screwed or nailed into and require removal. You may be able to use a hammer or chisel to remove them but it's best to lay down dust sheets before starting any work.

Once the access panel is removed, you can begin working on the sash. Utilize a flat bar or chisel to pull the tiny parting beads from their grooves. They are typically wedged into or nailed but can be snipped out, so it's worth taking your time. If the sash is in place, pry out the mortise and tenon joints using pin punch and hammer or screwdriver, and then take out the wood pegs attached to each piece. The sash should be able move freely, however it might require some lubrication in order to feel less stiff.

Determine the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the chain or cord and secure it as in Step 6 above. You can either employ a hammer and screws or nails, but nails are less likely to cause damage.

If you don't have a kit that replaces the old counterbalance system it's best to keep the original weights for balancing in place. It's cheap to purchase them from a salvage store and they'll be easy to install once you've got the sash open. Based on the size of your window one or two sashweights could be needed to keep it open.
